the offset is et15, and theyll have 45 profile tyres on, should be the same outer diameter of stock steels, but will they be too wide? both for internal parts (sus etc) and arches?
also should add the car will be lowered 50mm at the rear an 75mm up front, cheer for any help

p.s. ive measured myself and they seem to be super close to fitting perfectly, just dont wanna fork out hundreds to find theyll scrub :/
